Because the fixing device is disposed inside the housing 1 of the connector 100, there is no need to provide an additional space on the mounting plate for the fixing device. As a result, the mounting space on the mounting plate can be saved.
As shown in Figs. 1-4, according to an embodiment, the fixing device includes a first hole 131 formed in the inserting part 13, a screw nut 132 integrally formed on the inserting part 13 at the first hole 131, and a second hole 231 formed in the bottom wall 201 of the frame 20 of the conductive contacting member 2. When the conductive contacting member 2 is inserted into the receiving space of the housing 1, the first hole 131 aligns with the second hole 231. As a result, as shown in Fig. 7, a screw bolt 133 can pass through a mounting hole (not shown) on a mounting plate 200, the second hole 231 and the first hole 131 in this order and be secured on the screw nut 132, so that the connector 100 is fixedly connected to the mounting plate 200.
According the above embodiment, since the screw nut 132 is preset on the connector 100, when the connector 100 is mounted to the mounting plate, it is not necessary to mount the screw nut on site. Thus, the connector can be mounted conveniently and the mounting time can be reduced.
According to an embodiment, the screw nut 132 is a self-locking nut which is pressed and connected integrally on the inner surface of the inserting part 13 of the housing 1 during the process of manufacturing the connector 100. Therefore, the screw nut 132 is fixedly connected to the inserting part 13 and it is not necessary to bore a hole in the inserting part 13 while the connector 100 is mounted, thus, it is not necessary to bore a hole in the thinner inserting part 13. As shown in Figs. 1-4, according to an embodiment, the first hole 131, the second hole 231 and the screw nut 132 are positioned on a longitudinal central line L of the bottom wall 11 of the housing 1. Thus, when the connector 100 is fixed to the mounting plate 200 shown in Figs. 6 and 7 by the screw nut 132, the connector can be stably mounted on the mounting plate as compared with the case where the screw nut is positioned on other places.
According to an embodiment, there are two first holes 131, two second holes 231 and two screw nuts 132, respectively. With this configuration, it is easy to mount the conductive contacting member 2 on the central line of the bottom wall of the housing 1. However, it should note that the numbers of the first holes 131, the second holes 231 and the screw nuts 132 are not limited.
As shown in Fig. 2, each of the side walls 12 of the housing 1 includes a first side wall portion 12a connected with the bottom wall 11 and a second side wall portion 12b which is positioned at the inserting part 13 and separated from the bottom wall 11. There is a vertical slit 12c formed between the first side wall portion 12a and the second side wall portion 12b. The slit 12c can serve as a stopping and positioning member for stopping further movement of the frame 20 of the conductive contacting member 2 when the conductive contacting member 2 is inserted.
As shown in Figs. 1-4, a lower portion of each of the second side wall portions 12b of the housing 1 flares outward so that the conductive contacting member 2 can be easily inserted into the housing 1 and will not shake in a left and right direction.
As shown in Figs. 1 and 3, when the conductive contacting member 2 is inserted into the receiving space of the housing 1, the terminal part 21 of the conductive contacting member 2 is positioned between the first side wall portions 12a of the housing 1, and the frame 20 of the conductive contacting member 2 is positioned between the second side wall portions 12b of the housing 1. For this purpose, the connector 100 is manufactured so that a length of the second side wall portion 12b or the inserting part 13 is approximately equal to the length of the frame 20, and a length of the first side wall portion 12a of the housing 1 is approximately equal to a length of the terminal part 21 of the conductive contacting member 2.
As is clearly shown in Fig. 2, each of the side walls 12 of the housing 1 is formed with a first engaging means 121, and each of the side walls 202 of the frame 20 of the conductive contacting member 2 is formed with a second engaging means 221. As shown in Figs. 1 and 3, the first engaging means 121 engages with the second engaging means 221 when the conductive contacting member 2 is inserted in the receiving space of the housing 1.
Specifically, according to this embodiment, the first engaging means 121 is a rectangular opening formed in each side wall 12 of the housing 1 at the second side wall portion 12b, and the second engaging means 221 is an elastic sheet projected from each side wall 202 of the frame 20 of the conductive contacting member 2. The elastic sheet may be formed by cutting a portion of each side wall 202 of the frame 20 and bending the cut portion.
When the conductive contacting member 2 is inserted into the receiving space of the housing 1, the elastic sheets on the frame 20 elastically contact the inner surfaces of the side walls of the housing 1 so that the conductive contacting member 2 can be stably inserted. As the conductive contacting member 2 is inserted continuously, the elastic sheets on the frame 20 enter the respective openings in the side walls of the housing 1. Therefore, the elastic sheets may assist to position and fix the conductive contacting member 2 and the housing 1. The elastic sheet may be provided to project from the side wall of the housing 1 slantwise in a direction opposite to a direction for inserting the conductive contacting member 2 into the housing 1. In this way, once the elastic sheets enter the respective openings in the side walls of the housing 1, the elastic sheets can prevent the conductive contacting member 2 from moving and escaping from the housing 1 in an opposite direction.
Besides the first engaging means and the second engaging means in the above forms, of course, a person skilled in the art can conceive of engaging means in other forms, such as a projection and a recess.
As is clearly shown in Figs. 3 and 4, a U-shaped cutout 110 is formed at an end of the bottom wall 11 of the housing 1 opposite to the inserting part 13 for guiding and inserting a bus bar 300 (as shown in Fig. 6 and 7). Further, the bottom of the U-shaped cutout 110 is used as a stopping and positioning part when the bus bar 300 is inserted. Preferably, the two sides of the opening part of the U-shaped cutout 110 are chamfered so as to guide and insert the bus bar 300 better.
Each of top ends of the first side wall portions 12a of the housing may bend inward to form an elongated opening 111 aligning with the U-shaped cutout 110 in the bottom wall of the housing so as to guide and insert the bus bar 300 better.
As shown in Fig.2 , the frame 20 of the conductive contacting member 2 includes a narrow upper portion 20a and a wide lower portion 20b and the upper portion 20a is positioned at a center of the lower portion 20b so that the frame 20 has a cross section of a generally " ΰ" shape. The terminal part 21 is extended from a front end of the upper portion 20a, and the lower portion 20b is adapted to be fitted over the inserting part 13 of the housing 1. The lower portion 20b has a width approximately equal to that of the housing 1.
As shown in Figs. 2 and 5, the terminal part 21 includes two rows of terminals extended from the two side walls 202 of the frame 20 at the upper portion 20a of the frame 20. The first row of terminals consists of a plurality of first terminals 21a. The second row of terminals consists of a plurality of second terminals 21b. Each terminal is of an elongated bar shape and is bent into a generally S-shape. Alternatively, each terminal may has other shape which is adapted to elastically clamp the electric bus bar easily. In use, the bus bar 300 shown in Fig. 7 is inserted between the two rows of terminals from a front end thereof and is elastically clamped between the two rows of the terminals.
Further, as shown in Fig. 5, the first terminals 21a and the second terminals 21b are interleaved with each other between the two rows of terminals. By this arrangement of the terminals, the connector can be ensured to have a low contact resistance.
The housing 1 and the conductive contacting member 2 of the connector 100 according to embodiments of the present invention can be separately manufactured, and then are assembled together in the way as described above. The housing 1 and the conductive contacting member 2 each can be manufactured from a single plate by normal cutting, punching, molding or other processes.
Fig. 6 shows a perspective view of the connector 100 in use according to an
embodiment of the present invention. Fig. 7 is a front view of the connector shown in Fig. 6. As shown in Figs. 6 and 7, an assembled connector 100 is fixed on the mounting plate 200. The connector 100 is fixed onto the mounting plate 200 by the following steps: placing the connector 100 on the mounting surface of the mounting plate 200 having a mounting hole formed in advance therein, with the bottom wall 201 of the frame 20 exposed outside the inserting part 13 being in contact with the mounting surface of the mounting plate 200 and the second hole 231 in the bottom wall 201 of the frame 20 and the first hole 131 in the inserting part 13 of the housing 1 aligning with the mounting hole in the mounting plate 200; inserting a screw bolt 133 in the mounting hole of the mounting plate 200 from the side of the other surface (bottom surface) of the mounting plate 200 opposite to the mounting surface, and causing the screw bolt 133 to enter and be screwed into the screw hole of the screw nut 132 at the first hole 131 while passing through the mounting hole in the mounting plate 200, the second hole 231 in the bottom wall 201 of the frame 20 and the first hole 131 in the inserting part 13 of the housing 1 in this order, so that the connector 100 is fixed on the mounting plate 200. At this time, the front portion of the housing 1 is projected beyond the front edge of the mounting plate 200 so as to facilitate the inserting of the electric bus bar 300. Then the bus bar 300 is inserted between the two rows of terminals 21a and 21b of the conductive contacting member 2 from the front side of the housing 1 through the U-shaped cutout 110 and the top opening 111 of the U-shaped housing 1, and thus the connection and mounting of the connector 100 is finished. In this state, when a power is applied, the power can be transmitted to the mounting plate 200 from the bus bar 300 through the conductive contacting member 2 of the connector 100.
